To all whom it may (mm-cm:

Be it known that I, Aunnniss M. Sonmou- SEN, a citizcn of the United States, residing: at iiiil'uuukccq in tho county of hiiilwoulccc and Shite of iiTisconsin; have invcntccl (391" tuiu new zuul useful linprovcmcnts in Fan tenings for Bun'ipcrs; and i do declare the following to he a full. clear, zuul exact cicscription. of the invention. such as will cnahlc others skilled in the art to which ii on pertains to make and use ihe same.

This invention mimics to improvements in fastcnings for the humpei's of motor vc hiclcs.

One object of tho invention. is to provide a bumper fastening which may bu rcailil y' applied to ihc frame of any motor vehicle to secure the bumper in plocc ihc'rcou.

Another object is to provide a fastening for bumpers which may be adjusted to support the bumper at any losirccl position.

A further object is to provide a fasicniug of this character which will. be simple strong, durable and inexpensive in construclion, cflicient and reliable in operation and well adapted to tho purpose for which. it; is designed. 1 i

With these ond other objects in View, the invention consists of certain :uovcl fcuiurcs of construction, and the combination and arrangement of puris us will he more fully described and clcimccl.

In izhc accompanying drawings: Figure 31 is a; plan View of a portion of the mm cud of a motor vchicic showing the application of the invencion :ioi" fastening; lihc huinpci" to the frame of the vehicle. Fig. Q u (utoil perspective vicw of the fowworci cud oi one of the siic loui'opi? the chassis 01 supporting ironic of tho vehicle and one our:

Eefcrring morc particularly to the drawings, l fienotcs the bumper or l'mfiei' bar which may be of the usucl'construction and which is disposeci. in front of the vehicle in the usual. manner. The bumper 1 has arijustobly secured thereto near its ends 'i'- coupling 52 in the rcarwohdly extending brunch of ouch of which is sccuhcd c bullies om supporiing and guiding rod 3. The coupling 2 is adjustohly secured to the bumper loan 1 hy o sol; screw or other suilr ohlo iuslening device 4-. Thu supporting rod S has a sliding; engagement at its inner enrl with u slocve 01 tubular guicling and supporting member 5 of a loufier supporting! bracket 6 which forms part of my improved fastening. Arranged on the supporting rocl 3 between the outer curl of the siccvc 5 and the inner end of the coupiing 2 is a coiled huffcr spring 7' which yicldingly project-i uml hoiols the rod 3 and the bumpcz' box 171 in u pi'ojcctccl position and uhsorhs tho shocks which are produced when the humour rod is hi'ought into forcible. engagement with an obstruction. The roci 3 cxiieniis entirely through {her slccvc 5 and is hold in operative engagement thcccwiih by a, cotter pin 8 01 similar fusicning om'nugccl through hhc in- F191 cnoi oi the cool as shown.

The" bolt M is preferably provioccl with u lookiug Washer 15' whcrchy the casual unscrewing of thc hoii; is prevented-l. The plate 19; is pl'oviocd on its outci" surface with on onnuloi' scrics of iccth or corrugations 16 which co-ucl; with tho teeth or corrugations 11. in; tho plate 9 and rigidly hold these ports in opcmliivc engagement when clumped to gather by lhc bolt M. 'By providing lhc plaics 9 and 1% "with corrugations or teeth us heroin shown, un l (lcsci'ibcd it will he soon that the bracket member 6 oi. tho fastening may be adjusted to holol the sleeve sides of the side bars B of we supporting frame or chassis of the vehicle as shown. "ne attaching plate 12 is eecui'eiy damped to the bar B by upper ami lower damping bolfs 18 which have their iieeeci ends counter-sunk and rigidiy secured in the plate l2 and which project inwardly from saici pinte :bove and below the bar B as shown. With the liu-eznle i ends of the be is 18 is engaged a damping plate 19, said piate being drawn inh tight. clumping engagement "With the bar 15 of the vehlele frame by damping nuts 20 which are screwed onto ihe threaded ends of the bolts 18 as clearly shown in Figs. 1 and e of the drawing. The plaie 19 when thus arranged. c-o-acts with the plate 12 of the fastening to .z'igioiiy secure the latter i0 the bar fee a the bracket men'ibei" 6 thereto iii any position, thereby supporting :"ne bumper her at the desired distenee in from vehicle.

From the foregoing description taken in connection with the eceempanying dram ings, the construction and oeeratien of the invention will be readily uncierstood Without requiring a more extended oxpianetion.
